Dumped In The Swamp
Its PA’s largest swamp and has no confirmed bottom. The swamp has exceeded depths of 200 feet strait down, swallowed an entire locomotive, and a bulldozer/crane. I-79 runs through it on a floating bridge because there is no bottom to affix stable structures.
Countless dive teams have tried to locate it and have even sent robots to find it, only to lose contact with the robots and then never resurface. Countless bodies are rumored to be dumped in the swamp, never to be found again.
